Why do more couples have sex on this day?

According to the Popular Health Network, there are many interesting rules in human sex, which are as precise as a calendar.

1. Every September 16th, millions of people around the world celebrate their birthdays

It is the day with the most birthdays in the world. This also shows that winter is the peak period of pregnancy.

2. December is the peak month for pregnancy, while August is the low point for pregnancy.

The University of Texas study believes that "from a biological point of view, the reason is that sperm quality is not high in summer, and the long days and short nights affect ovarian function; while in December, there are many holidays and the weather is cold, so people have more concentrated sex and are more likely to get pregnant."

3. The most people have sex on Friday, while Monday is the least popular time for sex

The data comes from the 2011 sex survey conducted by Fun in Tokyo. The survey covered the time period, location, frequency, and identity of sexual partners of men and women in Tokyo. The results showed that 56% of people have sex on Friday, followed by Saturday at 30%, and then Thursday, Wednesday, Sunday, Tuesday and Monday.

4. 83% of people like to be intimate on rainy or cloudy days

A large-scale survey conducted by a US condom company showed that people are more likely to have a desire for intimacy on rainy days, and their feelings for each other will become closer.

5. Some people refuse to be intimate because of the hot weather, while others refuse to be intimate because of the cold weather. The former is twice as likely as the latter.

A survey in the United States found that 35% of people have refused intimacy multiple times because of hot weather, while 19% have refused intimacy because it was too cold.

6. The probability of intimacy in the evening is 13 times that in the afternoon

People surveyed said that sexual behavior requires the right time and place. Although sexual desire is high in the afternoon, it is not suitable for sex. In the evening, after completing a day's work, it is more suitable for lovemaking.

7. Sexual activity will increase after work becomes stable

Researchers at the University of Lugano in Switzerland found that job instability can lead to a lack of sexual desire, but sex can be more harmonious for a period of time after work becomes stable.
